Later, she tweeted: "#shorthairDontcare" to a friend on the social medis site. Spears attached a blurred photo of herself wearing eyeglasses looking away from the camera while revealing a shoulder-sweeping bob haircut.

The former Nickelodeon star announced on Instagram that she is engaged to Jamie Watson, her boyfriend of three years, on March 2. She posted a photo of herself smiling while held in an embrace with Watson and in the picture she held her left hand up to show off the ring.

"Guesssss what??????" she wrote on Instagram followed by "#Hedidgood" as she captioned the photo of the ring solo.

Watson, 30, told the New York Post in January they had been dating on and off for three years. It will be the first marriage for Jamie-Lynn. She was previously engaged to Casey Aldridge, the father of her 4-year-old daughter Maddie.

Jamie-Lynn's engagement news comes two months after her older sister Britney ended her own year-long engagement to Jason Trawick, TMZ reported on Jan. 11. The news came a day after it was announced that Spears quit The X Factorafter just one season of being on the show.
